Jeff is interested in toning his abdomen. What muscles would you tell Jeff to exercise to accomplish his goal? What movements would best exercise these muscles?
Jeff should do exercises that flex and twist the trunk. The muscles he should target are the rectus abdominis muscles, and the external and internal oblique muscles. Sit-ups and twisting movements will stimulate these muscles. If he places a weight on his chest as he does sit-ups, it will produce faster results because the rectus abdominis muscle would be working against a greater load.
